    Working environment Indoors in a dry environment with max. temperature +45℃ and humidity no more than 80%. Do not use the machine 1) If it is with a damaged cord. 2) On a wet floor or when it is exposed to rain to avoid electrical shock. 3) If it has been dropped or damaged until it is checked or fixed by a qualified serviceman.
  • Page 17 This machine is well designed with air filters, so please clean up the filter with any foreign particles (recommended to clean up this filter weekly). 4) Clean the blowers both internal and external parts (especially for the fan cooling path), and remove surface dust if necessary. If more dusts are accumulated, it will cause deficiency for ventilation, temperature rising, vacuum power reduced, vibration increased and so it will cause machine broke down.

    C. Cable connection: when packaging MHD-230U and above models, it should separate the hopper and floor stand. During connection, airflow detecting signal, airflow adjusting signal and temperature control signal require metal connectors. See below wiring diagram (1) MHD-U and SD-H-SM are jointed by 2 groups of cables, and among which one group is hopper’s data cable jointed by 10PIN heavy-duty connector separately, and the other group is communication cable connected by 4PIN heavy-duty connector.

    6.1 Honeycomb-rotor 6.1.1 What is “honeycomb-rotor”? The main body of the honeycomb-rotor is a honeycomb, made by ceramic fibre and organic additives, sintered under high temperature with molecular sieve and silica gel, to be strongly bonded together and form a solid and hard surface. Not like common molecular sieve, which will produce dusts and fines to pollute raw materials when aging or become saturated requiring regular replacement, honeycomb-rotor offer unlimited long life and can be cleaned when it is polluted.
